AXLE-NUT WRENCH.-

SPECIFICATION forming part of Letters Patent No. 7o7,248 dated August19, 1902. Application filed August 10, 1901. Renewed Ma s, 1902. Isa-n1No. 105,322. (No model-) To all whom it may concern:

moving axle-nuts; and the object thereof is to provide a simple,inexpensive, and easilyoperated device whereby the work of removing theaxle-nuts may be speedily and easily accomplished. Y r

My improvement has, further, for its object to provide a wrench'forclamping the'hubband and nut, so that the nut may be unscrewed byturning the wheel in an opposite direction to the pitch of the threadsof the axle-spindle and to hold it firmly in .place and in position tobe again screwed'onto the spindle without the necessity of bringing thehands into contact with:the nut.

With these objects in viewmy improvement consists in the'peculiarcombination and novel arrangements of parts, as will be fully describedin'the following specification, reference being had to the accompanyingdrawings, in which'' Figure 1 is a perspective view of my improvement asin use.

the hub of awheel being shown in section.

Fig. 3 is a sectional elevation looking at right,

angles to that shown in Fig.2. Fig. 4 is-an end elevation. Fig. 5-isajdetail perspective view of the section, and Fig.6 is a detailperspective view of one of the clamping-jaws.

In carrying out my invention I employ a socket-section A, in one end ofwhich is pro-: duced a rectangular recess (1, adapted for thereceptionof a nut, the opposite end offthe section terminating in .a threadedshank-ct,-

and upon opposite sides of the section, near the socket end, arefoundears o in which are pivoted clamping-jaws B, the forward ends 5 ofwhich are broader than the shanks and have their vouter surfacesconvexed and serrated, adapting them for engagement with the innersurface of the hub-band, as will be explained later on. The rear ends ofthe shanks b are beveled and adapted for engagement .gaged.

In operation the socket is first placed on a Fig. 2ais a sectionalelevation of my improvementapplied to a nut,

with the innerj'surface of the hub of a handwheel nut O, the said hub 0having a threaded bore through which the shank a of the socket portion Ais adapted to work. The inner face of the hub terminates in anoutwardly-flaring collar-section 0, whose inner face is preferablyarranged on an angle of about forty-five.

nut of a vehicle-agile and the hand-wheel nut screwed upon the shank ofthe said socketsection, the bevel-surface of the hub contacting with theshanks of the clamping member, causing the inner end to be pressed intoward the ,center and the outer ends thrown outwardly, contacting withthe inner surface of the band of the hub until a firmhold is secured.Then by turning the wheel in the proper direction the'nut is removedfrom the spindle and will be held within the socket and in position tobe again screwed into place when desired.

It will thus be seen that the operation is exceedingly simple, and byreason of the leverthe disagreeable necessity of bringing the hands intocontact with the nut.

V I am aware that the broad idea of removing anut fromthe spindlebytheaction of the wheel is not broadly new; butI do claim by the novelcombination and arrangement of parts as shown and-described I obtain amore positive, durable, and easily-operated device than has heretoforebeen upon the market.

Having thus fully described my invention, what Iclaim. as new, anddesire to secure by LettersPatent of the United States, is-

1. In a wrench of the kind described, the combination of asocketportion. having one endterminating in a-threaded shank,clamping-jaws pivoted to .the said socket portion, and a hand-wheellnutadapted for'engagement with the jaws, substantially as shown anddescribed. i H o 2. In awrench of the kind described, the combination ofa socket portion having a threaded shank formed integral therewith, anda rectangular recess formed therein, clamping-j aws pivoted uponopposite sides of the said socket portion, a hand-wheel nut having itshub provided with a tapering annular recess and adapted for engagementwith the clamping-jaws, substantially as shown and described.

3. In a wrench of the kind described the combination of a socket portionhaving a rectangular recess produced in one end and a threaded shankprotruding from the opposite end thereof, ears formed on the said socketportion, clamping-jaws pivoted in the said ears, the heads of said jawshaving their outer surfaces convexed and serrated, and the shanksthereof extending past the end of the said socket portion,ahand-wheelhub adapted to operate on the said threaded shank, the hubthereof having a tapering annular recess, the inner surface of Whichbeing adapted for engagement with the shanks of the said c1ampingjaws,substantially as shown and described.
